Contact Calcshark
Calcshark is maintained by a small team, and we read everything that comes in. If a calculator has given you a result that looks wrong, we would genuinely rather hear about it than not, because a quiet error affects everyone who uses that tool afterwards.
The fastest way to reach us is email. We aim to reply within two working days, and we prioritise reports of incorrect calculations above everything else.
Email us
Typical response time is one to two working days. There is no contact form because a form would collect your details for no benefit over an email you already control.
What to write to us about
A calculator is giving the wrong answer
This is the message we most want to receive. Tell us which calculator, the exact values you entered, the result you got, and the result you expected. We check reported errors against the published formula and correct or explain within a few days.
You want a calculator that does not exist yet
Tell us what you are trying to work out and how you currently do it. Requests that describe a real problem are far more useful than a bare name, because they tell us what the inputs and outputs need to be.
You want to know where a formula came from
Most calculators cite their standard or source on the page itself, and our guides explain the derivations. If a particular figure is unclear or you disagree with an assumption, ask and we will point you at the reference.

Helping us reproduce a problem
Calculations run entirely in your browser, so we cannot see what you entered. To investigate a wrong result we need you to tell us:
- The page address of the calculator
- Every value you entered, including the units you selected
- The result shown, and the result you expected
- Your browser and whether you were on a phone or a computer
